Finally, sanity and logic in the midst of chaos
I think it is clear from this shot that Travis is planning to kill her. We can only see one hand, because the other is holding the butcher knife, not a rose. An unaware Moana is staring at his left ear, thinking about whether or not she's missing Desperate Housewives. The chandelier above has been photoshopped in--in fact the entire room has been, because they are actually on the deck of a sailboat, and he plans to push her corpse in the water afterwards. The candles in the foreground, however, are real, and the fact that they are slightly uneven on top proves that Travis had enough time to get to at least second base before we got to this point.
